The NDA government is 'trampling upon constitutional propriety and established conventions,' the Congress said.

Congress has termed this week's passing of the Finance Bill as a "sad" commentary on the conduct of Narendra Modi's NDA government. The opposition party also once again levelled 'Tax Terrorism' allegation against the NDA government.

"For the first time in the constitutional history, a bill has been passed in the Parliament which amends 40 different laws in one go," Randeep Surjewala, Congress's communication department head said. The bill was passed by the Lok Sabha this week during the ongoing budget session.

Surjewala accused the Modi government and Finance Minister Arun Jaitley of misusing the Bharatiya Janata Party's majority in Lok Sabha to "trample upon constitutional propriety and established conventions."

He went to allege that the government had used the Finance Bill, which was taken up as a Money Bill, to slip in amendments to 40 laws.

Under Parliamentary procedure, Money Bills are in the exclusive domain of the lower house. Rajya Sabha can debate on such bills, but can't ammend or reject them.

"The (passing of the) Finance Bill is a sad commentary on (the) conduct of BJP government which is hell bent on destroying the relevance of Rajya Sabha," Surjewala added.

Upping the ante against the central government, Surjewala further said, "The Finance Bill has unleashed a sordid culture of 'Tax Robbery' and 'Raid Raj'."

"It has also provided a window to corporate cronies to maintain a film of opaqueness in political donations. Tax Terrorism is flourishing and transparency is dead under BJP government," he said.
